Mine slag-based aerated building block and preparation method thereof
The invention discloses a mine slag based aerated building block and a preparation method thereof. The method comprises the following steps: carrying out ball milling on mine slag, quick lime, basaltand water, screening with a 100 [mu]m sieve mesh to obtain a prefabricated material, adding cement and gypsum into the prefabricated material, and uniformly stirring to obtain slurry; stirring sodiumbentonite, ammonium bicarbonate powder, an emulsifier and water, performing spray drying, heating at 60-70 DEG C for 1-2 h, adding cationic starch and water, grinding, then performing activation at 105-115 DEG C for 20-30 min, drying, and screening with a 100-mesh sieve so as to obtain a cationic starch-bentonite complex; and uniformly mixing the slurry, the cationic starch-bentonite complex, a sulfonated melamine formaldehyde resin, lignin fibers and water, carrying out mold pouring at a pouring temperature of 40-45 DEG C, carrying out pre-curing for 20-40 min, demolding, cutting, and carrying out steam curing to obtain the mine slag-based aerated building block.
本发明公开了一种矿山渣基加气砌块；本发明还公开了上述矿山渣基加气砌块的制备方法，包括如下步骤：将矿山渣、生石灰、玄武岩、水球磨，过100μm筛网得到预制料，向预制料中加入水泥、石膏搅拌均匀得到浆料；将钠基膨润土、碳铵粉、乳化剂、水搅拌，喷雾干燥，60‑70℃加热1‑2h，加入阳离子淀粉、水研磨，然后105‑115℃活化20‑30min，干燥过100目筛，得到阳离子淀粉‑膨润土复合物；将浆料、阳离子淀粉‑膨润土复合物、磺化三聚氰胺甲醛树脂、木质素纤维、水混合均匀，模具浇注，浇注温度为40‑45℃，预养20‑40min，脱膜后切割，蒸汽养护得到矿山渣基加气砌块。
